ReCIA
About the ReCIA PCB
ReCIA is an open source FPGA PCB design by jbilander, published on GitHub. It is a 2-layer board measuring 17.4 × 51.4 mm, with 6 components from 5 distinct parts.
Its main chip is the 10M02SCU169, from the FPGA family. Other key parts include the AMS1117-3.3 and 8520_DIP. By type, the board carries 3 ICs and 3 capacitors.
It belongs with the retro computing designs in this gallery.

A drop in replacement CIA for old Amiga Computers
This is WORK IN PROGRESS. If you generate gerbers and order PCBs from this source you are doing so completely at your own risk!.
Current design is based on an intel/altera 10 Max FPGA but this is mostly so we can signal tap and record how a real 8520 behaves. The oscillator on board is 10 MHz and the PLL on the Max 10 can take this clock and make a perfect 28.375 MHz or a 28.636 MHz clock signal which will be nice to base the logic on instead of the E-CLK.

ReCIA: common questions
What microcontroller does the ReCIA use?
The ReCIA is built around the 10M02SCU169, from the FPGA family.
How big is the ReCIA PCB?
The ReCIA measures 17.4 × 51.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ReCIA?
6 components, from 5 distinct parts. The full bill of materials is listed on this page.
Where can I download the ReCIA design files?
From the jbilander/ReCIA repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the ReCIA design in my own project?
The repository has no license, so all rights stay with jbilander. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ReCIA without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
